Application Scenarios & Design Considerations

Digital Temperature Sensor with 2-Wire Interface

Alternative Part Number

  • LM75BIMX-3/NOPB --: Pin-compatible I2C temperature sensor with similar accuracy and supply range, widely available and often used as a drop-in replacement for TMP175 in many designs.
  • STLM75M2F --: I2C digital temperature sensor with comparable resolution and accuracy, same SOIC-8 footprint, offering a second-source option with similar electrical characteristics.
  • MCP9808T-E/MS --: High-accuracy I2C temperature sensor with compatible interface and supply voltage, suitable as an alternative when slightly better accuracy is acceptable.
